海床冲淤变换属于长期行为,其海洋动力输入条件的概化处理是模型初始输入动力条件的一个关键问题。在本文中,利用波浪、潮流二维泥沙数学模型对长周期动力海床模型中代表数据输入的概化条件作了进一步的研究:采用比较代表条件与真实条件下多年实测平均海床冲淤强度近似以及把潮周期中具有平均意义的波浪过程概化要素叠加到潮流场中的方法分别对实际潮流、波浪数据进行概化处理的方法来模拟波流共同作用下的海床地形演变过程。并对黄河三角洲的胜利油田海区、岸线进行了验证计算。
Seabed scouring and silting is a long-term behavior, and its general treatment of marine power input conditions is a key issue for the initial input dynamic conditions of the model. In this paper, using wave and tidal current sediment mathematical model to further analyze the generalized data input in the long-term dynamic sea bed model, the comparison between the representative conditions and real conditions, Intensity approximation, and the method of superimposing wave elements with average wave process in the tidal flow cycle on wave tidal current. The actual tidal current and wave data are generalized respectively to simulate the evolution of the seabed terrain. The verification and calculation of the sea area and shoreline of Shengli Oilfield in the Yellow River Delta are carried out.
